Horatius Bonar addresses the confusion and instability in contemporary theology, emphasizing the overwhelming number of changing opinions and doctrines that can lead believers astray. He warns against the allure of novelty and the dangers of fickle minds that easily shift from one belief to another without a firm foundation in truth. Bonar stresses the importance of a tender conscience and reliance on God's unchanging Word for guidance, rather than succumbing to the whims of popular opinion. He encourages believers to seek wisdom from God and to trust in the eternal truths of Scripture amidst the chaos of modern thought.
